Ever want to use your iPad as a secondary display for your Mac? Now you can using Duet. Duet allows you to mirror your iOS device or use it as an extended display! Download it from the App Store, install it on both your Mac (or PC) and your iOS device, and connect the two via USB and you are ready to go. Once linked you can use the touch screen as your mouse and use your iOS device as a secondary display for your Mac or PC!!
When running Duet, I was impressed in how smoothly it operated. I noticed no lag and with the ability to adjust frame rate and resolution, the result is a fairly seamless integration. One nice feature is the automatic adjustment in resolution whether in landscape or portrait view. You can switch the FPS (frames per second) between 60fps and 30fps. However, I noticed it ran perfectly at 60fps. Movies synchronize perfectly with the audio which is very cool.
I am discovering that there are tons of apps out there that have similar functionality including iDisplay. This app allows you to use your iOS device as a display wirelessly, however, both the computer and device need to be connected to the same Wi-Fi network. This can be beneficial for some applications but for those looking to keep their displays confidential and secure, Duet is certainly safer as it is wired and therefore is more secure and you don’t have to depend on a consistent signal.
All in all, Duet is great app and is definitely worth checking out!
